screen: Introduce argument to windows command

A string escape can be passed which makes the windows command
much more flexible. The default string escape if no argument
is passed is "%n%f %t " which is intended to rebuild
the same output the windows command would give as good
as possible (slight changes with the flags can happen).

This command is also not be limited in output size
(the windows command is limited to 1024 bytes).

The windowsx command can be queried (-Q command) and
this is its main purpose (be able to query the exact
window list status of an active screen session from
shell).
